Reliable solutions
for all your photonics needs.
Quality solutions
Based on size, reliability and cost, diode lasers from Coherent are the first choice for single-mode diode
lasers (<100 mW) for scientific, OEM, medical or industrial applications. With the highest quality design
and superior beam quality, our high-performance diode laser modules can meet your exact needs.
APPLICATIONS
• Confocal
Microscopy
Patented AlignLock technology
Only Coherent allows the laser beam to be simultaneously collimated and aligned. Other diode laser
manufacturers can do one or the other, but not both. Patented AlignLock™ lets you know that the
pointing stability and thermal/mechanical design is world class (US 5,111,476 and US 5,121,188).
• Cytometry
Rock-solid potting
• Genomics
Diode modules are engineered for protection from mechanical shock, optimized for thermal
conductivity and vibrationally damped, so factory alignment is rock-solid and reliable.
• High-Throughput
Drug Screening
• Industrial Alignment
Electronic protection
Our diode laser modules are protected from electrostatic discharge (ESD) and are fully shielded with
reverse polarity protection, meeting MIL-STD 1686B/Level 2 requirements, up to 4000 volts. With
Radius™ and CUBE™ lasers, protection exceeds Level 4 ESD at 15,000 volts.

and Measurement
Diode laser modules are smaller, require less power, generate less heat and have longer lifetimes than
other laser sources. Our laser modules are configured as elliptical beams, circular beams or line
generators with optional adjustable focus to increase or decrease the divergence.
Temperature, wavelength and power
Temperature fluctuations can adversely affect diode lasers. For example, at 50°C typical red diode
lifetimes are approximately 6,000 hours. However, when the diode is actively cooled, the expected
lifetime becomes >30,000 hours. Both the Radius and CUBE systems offer an internal thermal-electric
cooler (TEC) drive for complete thermal management and optimization of the diode laser’s reliability
and performance.
All Coherent diode modules feature constant power drive. Internal photodiodes provide for a closedloop power drive so that the output power is constant over temperature and lifetime. Beware of other
modules with only constant-current drive, which have the disadvantage of continual power loss over
the life of the laser. Coherent laser modules provide stable power—always.
We also offer the only ultra-low-noise (ULN) diode laser modules, which feature no mode-hop noise and
no warm-up time, with RMS noise levels of <_0.06% over temperature and lifetime of the module
(bandwidth <10 MHz). ULN lasers are ideal for instrumentation and particle counting applications,
providing the maximum system dynamic range so you can reliably count even the smallest particle.

Diode Laser Systems
CUBE lasers are high-performance, full-feature diode
laser systems. Each contains a laser head, power supply,
cable, and control box. The system is designed to be
one of the easiest to set-up and use. The CUBE delivers
the most power, stability and performance—in the
smallest package—with the best value.
A complete system
All CUBE electronics, optics and thermal management
are built into the head. Every system includes a fullfeature cable that lets you access all the features inside
the CUBE. A compact 6V power supply, a control box for
safety features, and USB software to drive the laser are
also included.
The CUBE
The CUBE offers you full control. First, the CUBE can
work as a CW laser with a convenient auto-start mode.
The CUBE also offers a digital input connector, located
on the back panel, to drive the laser up to 150 MHz with
a TTL source. Users can then command the CUBE to
change the power level, either through the RS-232 or
USB. For analog modulation the CUBE offers a separate
analog input, located on the front panel of the control
box, which allows variable power control up to 350 kHz.
For high dynamic range the digital modulation and
analog power controls offer modulation depths greater
than 250:1. For maximum flexibility in your application
the CUBE also offers mode selection for constantpower or constant-current drive. The versatility of the
CUBE includes CW, digital control, analog control and
variable power operation.

•
With all the electronics inside the head, the control and
instrumentation are available through the 15-pin
connector on the laser’s back panel. The interlock input,
laser enable input, or auto-start mode provide control.
Instrumentation on the CUBE gives you a laser-ready
output, laser output power (actual laser power in an
analog signal), baseplate temperature and general fault
conditions. Every CUBE laser has a built-in photodiode
that measures the laser final output power. The
photodiode enables closed-loop power stability and
allows you to know the laser power via the analog
output or computer. CUBE lasers are also equipped
with dual-temperature probes, which control thermal
management and display both the diode and baseplate
temperature. Overall, the CUBE offers complete control
and instrumentation without the need for additional
equipment.
www.Coherent.com
Multiple CUBE Connections
CUBE lasers make it possible to configure multiple
lasers into the same computer. Using the USB can
allow up to 127 CUBE lasers to be connected on a
single computer. The CUBE connection software will
display each laser on its own control panel. The
CUBE also has intelligence, allowing it to report
which version (375 nm, 405 nm, etc.) is on the port,
so you can easily drive multiple lasers
simultaneously.

The Software
The CUBE includes a full-feature software interface for Windows 2000 or Windows XP with multiple
pages of status, control and configuration options. The home page includes an instrumentation
dashboard for power, current, diode temperature and baseplate temperature. Buttons control laser
on, mode, and power. A counter changes every one hundredth of an hour to show the actual ‘on’
time of the laser. The CUBE connection software makes it easy to use with help screens that feature
descriptions, graphics and other assistance.
Home Screen
The Home Screen allows for computer control of the
CUBE. Control laser On/Off, set laser power and change
operating modes.
Options Screen
The Options Screen allows for configuration choices on
settings such as laser current display, 5-second delay,
external analog power and laser diode temperature.
Terminal Screen
The Terminal Screen allows for direct communication to
the CUBE through the command line. Scripts can also be
executed and set to loop. The Terminal Screen can accelerate
the learning curve for laser control in embedded applications.
Status Screen
The Status Screen shows the details of the laser from
serial number to operating hours. A separate Fault
Screen also shows any faults from an interlock fault to
over-temperature.

Diode Laser Systems
The Control Box
To comply with the CDRH safety requirements for a Class
IIIb laser, the CUBE includes both the shutter on the front of
the laser and a separate control box. The control box
includes the key switch that activates the laser, a fivesecond power-on delay, an interlock RCA jack on the back
panel and a laser emission indicator. (For countries requiring
a second laser emission indicator, a second lamp that
connects to the cable I/O connector can be purchased
separately [part no. 1079150].) The control box also offers a
front panel BNC connection for the analog power control,
which can use an external voltage source (0-5V) to change
the CUBE’s output power.
Also included with each CUBE is a USB cable, which allows
the laser to plug directly into any Windows* 2000 or
Windows XP system.
The Cable
The CUBE’s full-feature cable allows access and control to all
its capabilities. The cable offers four separate lines: for
power, I/O, control box, and RS-232. The I/O cable is labeled
with the signal’s name, pin number, and description so you
can easily connect to the eight (8) separate laser
control/instrumentation signals. For example, connect a
voltmeter between pin numbers 2 and 7 and instantly the
meter is now reporting laser power with 2V equivalent to
100% laser output power. Or connect the convenient Second
Emission Lamp [part no. 1079150] as an additional safety
measure.
Reliability
The CUBE is fully protected from electro-static discharge
(ESD) to Level 4 standards and is also equipped with
temperate shutdown systems to protect the laser diode. The
diode and optics are temperature-controlled through a TEC
to provide the optimal performance and maximum lifetime.
Reliability is the priority—within every CUBE is a computer
processor controlling all the aspects of the laser drive,
thermal systems and protection measures.
The Power Supply
The CUBE, which has been designed for easy integration
into your system with a single power supply input, can
accept from 4.8V to 6.5VDC. Every CUBE system comes
standard with a compact 6VDC supply with a power switch
and an LED. The power supply is equipped with an IEC320
universal input, which allows most computer-style power
cords to be easily used with your country’s power (U.S. -style
power cord is included).
The RS-232 cable can plug the laser directly into a computer
for remote control and instrumentation.
Control and I/O
The control box is conveniently connected to allow required
safety features and analog power control from the front
panel BNC.
CUBE systems offer an extensive list of commands that
can be executed through the RS-232 or USB. Please visit
www.coherent.com and download the CUBE User
Manual or the CUBE help screens for a full description
of the commands and I/O.

Radius
Diode Laser Systems
Radius lasers are full-featured, high-performance, CW
diode laser systems that include a laser head, power
supply and optional control box. Designed for
convenient mounting into a HeNe laser holder for fast
and simple integration, they deliver power, stability and
performance in a complete package with the best value.
Adjustable Focus Radius lasers allow faster and easier
system integration. When optimizing the beam for best
focus or fiber launch, the adjustable focus eliminates
the need for an expensive beam expander. Instead, a
tool (included) adjusts the beam divergence through
the front shutter port.
Mounted on a large TEC, the diode laser and optics
remain at a constant temperature of 22°C. A heat sink
with an internal fan removes the heat. The closed-loop,
constant temperature keeps the wavelength constant,
minimizes mode-hops and maintains power stability.
Extra Photodiode
The Radius 405-30EP features an extra photodiode that
provides the best power stability over time.
Circular Beam
The patented micro-lens technology and aspherical
optics of the Radius 635-25 circularize the output of the
diode laser to better than 80% with a typical M2 <1.2.
The optional control box—with a key-switch, 5-second
power-on delay, emission indicator and interlock—
allows the system to comply with CDRH safety
regulations. The control box plugs into the side port of
the Radius.
The side port can also be used to modulate the laser
on-and-off as fast as 5 Hz (100 Hz for the Radius 635)
through the interlock control input. This modulation
can be used to extend the lifetime of the diode by
enabling the laser to be ‘on’ only when needed—while
the thermal system remains constant for improved
stability.

•
www.Coherent.com
Side Port
Using a side port, users can vary the diode
temperature in order to change the center wavelength
by ±1 nm (635 nm diodes). Varying the temperature
adjustment also allows users to avoid modehops, thus providing the maximum
coherence length.
•
[email protected]
Radius 635 specifications are equal to or better than most HeNe lasers in most
applications. Radius lasers also cost less and come in a smaller package. Both
power stability and pointing stability are superior with the Radius. Warm-up time
and output power over the laser’s life are also far superior when compared to the
HeNe. For all the details, please see the Radius 635 Competitive Comparison,
found on the Radius page of our website, www.Coherent.com.

The mounting of any laser is important to extend the stability
of the beam over time and temperature. The success of the
Radius Mount is the result of significant design research and
testing. The Radius Mount provides proper mechanical
positioning and allows for the system to have unobstructed
airflow and a full view of all labels. The safety shutter is easily
accessible, and the rear panel and side port are also
unobstructed for access and connections.
The dual V-block design provides proper positioning of the
laser tube, and the top clamps with the spring/ball hardware
provide the proper compression. This mount offers several

ULN
Diode Laser Modules
ULN-Series diode laser modules are designed for
applications that require particularly low noise or
mode-hop, noise-free operation. Sophisticated drive
electronics are used to ensure low noise output. Typical
RMS noise is 0.06% or better for detector bandwidth
from 10 Hz to 10 MHz, with practically no warm-up
time.
MicroBlaze™ beam circulation technology produces a
high-brightness, diffraction-limited circular beam that
is fully collimated with low divergence.
Overall, these low-noise, compact LabLasers are ideal
replacements for HeNe lasers, which require higher
power and generate more heat.
Applications include genomics, particle counting, flow
cytometry, optical storage, confocal microscopy, high
throughput drug screening, and spectroscopy. They are
also ideal for biomedical instrument design.
The ULN-Series features an alternative solution to the
mode-hop problem. Rather than regulate temperature,
a special modulation is used to force the laser into a
multi-longitudinal mode.
spectrum. The movement does not allow abrupt
changes, so the system operates as if there were modehops. The result is low RMS noise (~0.06%), which is
stable over changes in temperature and the life of the
diode laser module.
• ULN stabilizes both power and noise during
temperature changes (note that wavelength varies
with the standard temperature coefficient of the
diode, ~0.2 nm/°C).
• ULN controls noise over the lifetime of the laser and
will not develop mode-hop noise as the laser ages.
• ULN does not change the spatial qualities of the
laser beam, so the beam can be focused to the same
spot size, profile and shape.
The ULN laser is sold with a triple output power supply
to provide the necessary +5V and +12V to drive the
laser.
Use the LabLaser mount [part no. 0221-449-00] for
convenient heat sinking and mounting with adjustable
alignment.
While a normal laser will operate in a single-mode
longitudinal or oscillate between two strong modes,
the modulation creates several modes of lower
intensity. As the laser temperature increases, these
modes move like a caterpillar across the wavelength

ULN Series
ULN circular diode laser modules create a 1 mm circular
output beam using MicroBlaze patented technology.
This is a technique that accurately positions a fiber
microlens inside the diode laser cap. The microlens
uniquely corrects the divergence of the fast axis. Once
corrected, the beam shape changes from elliptical to
circular, providing maximum power transmission and
less astigmatism than other methods. The circular lowdivergence beams have almost no astigmatism and a
total wave-front error typically less than λ/10. The M2
beam quality factor is typically 1.2 or better. These diode
laser modules produce a beam of such high quality
that they can replace more expensive HeNe lasers in
many applications.
Compact, Rugged and Reliable
Our miniature laser modules are superb choices for
many applications demanding affordable, compact
lasers. Using AlignLock technology, all modules are
optimized for thermal conductivity, protected from
mechanical shock and deliver superior pointing
accuracy and stability. These compact, rugged and
reliable diode laser sources also have a sophisticated
internal driver/controller circuit, which provides both
surge and reverse polarity protection. The nominal
operating temperature range is -10 to +40°C. Diode
lifetime will be greater at lower temperatures.

Technical Note
Wavelength vs.
Temperature
Wavelength vs. Temperature
As shown in the table, red laser diodes have a
larger wavelength-to-temperature coefficient.
A special property of diode lasers is that the temperature
of the device affects the lasing wavelength. So adjusting
the temperature of a diode laser can be used to “tune” the
wavelength. The temperature can also be used to avoid
mode-hops. Mode-hops occur at certain temperatures when
the diode is beating between two wavelengths. By using
temperature controls it may be possible to center on a single
mode for longer coherence length and lower RMS noise.
Please note that as a diode ages, the wavelength also
increases slightly, typically <0.5 nm over the entire life of
the diode.

Higher diode temperatures can increase the wavelength.
However, this shortens the lifetime of the diode. Cooler diode
temperatures can reduce the wavelength and extend the
product life, but this can reduce the dew point and could
cause condensation on the optics.

Cross-Hair
Line Generators
Cross-Hair Line Generators deliver two sharp, highbrightness, fan-angle lines at 635 nm. These adjustablefocus cross-hair generators are ideal for long-life
projection and industrial applications. The adjustable
focus allows the width of the line to be focused, while
the length of the line remains fixed. The line can
typically be focused as small as <0.1 mm at a distance
of 10 cm or can be focused to as small as ~0.4 mm at
a distance of 1.0 meter.
The front knob allows for easy adjustment of the line
width and focus location. During adjustment the optics
do not rotate and focusing action is even and uniform
while beam alignment is maintained.3 A locking ring is
used to secure the focus in any position. Use the VLM2
mount [part no. 0221-437-00] for convenient heat
sinking and mounting with adjustable alignment. For
lasers without a connector, order plug no.1057734.

Focusable
Diode Laser Modules
Focusable diode laser modules combine the technology
of high-quality diode lasers with superior optics,
sophisticated electronics and rugged alignment
packaging. These modules can also be used in many
applications to reduce the requirements for external
optics. The result is an overall system that is smaller,
simpler and less costly.
The adjustable focus is a great benefit for many
applications. For machine vision, particle
measurements and inspection—and their inherent
need for direct measurements—the beam can be
focused at a distance for the smallest spot size to
optimize the system resolution. For fiber launch the
adjustable beam can also optimize the focus spot
position to achieve the ideal coupling efficiency. For
instrumentation applications with multiple laser
sources, the adjustable focus can match the red laser
beam properties to another laser to simplify
integration requirements.

Advantages of the Focus Feature
The focus feature can be used to:
Focusable elliptical diode laser modules offer
exceptional beam quality with a typical M2 of 1.4 or
better in a typical 1 x 3 aspect ratio.
• Adjust the beam to move the focus spot location
when an external objective lens is used. This is
especially useful when matching multiple wavelengths into the same beam focus position.
Focusable line and cross-hair generators deliver sharp
lines with adjustable line width, while the length of
the line remains fixed. The line can be typically focused
as small as <0.1 mm at a distance of 10 cm or can
be focused to as small as ~0.4 mm at a distance of
1 meter.
• Adjust the beam propagation so that it diverges
to create a larger spot at the target for broader
illumination.
• Adjust the beam so that it converges to create a
specific focus spot size at a certain working distance.
• Adjust the beam so that the beam waist is at a
particular point in space.
Focusable Diode Laser Modules
Focusable circular diode laser modules create a 1 mm
circular output beam using MicroBlaze™ patented
technology. This is a technique that accurately
positions a fiber micro-lens inside the diode laser cap.
The micro-lens uniquely corrects the divergence of the
fast axis. Once corrected, the beam shape changes
from elliptical to circular, providing maximum power
transmission and less astigmatism than other
methods. Diode modules with a 3 mm beam are also
available. These modules feature a multi-element
spatial filter that produces a large, clean, circular beam
with an ~3 mm diameter.
• Adjust the beam at the laser to reduce the need for
expensive and bulky adjustable beam expanders.
Circular 1 mm Beam
Circular diode laser modules produce a ~1 mm near-diffraction-limited beam. The circular low-divergence beams have
almost no astigmatism and a total wave-front error typically less than λ/10. The M2 beam quality factor is typically 1.2 or
better. These diode laser modules produce a beam of such high quality that they can replace more expensive HeNe lasers
in many applications. Circular diode laser modules are also smaller, require less power and generate less heat than
traditional HeNe laser sources.

Line Generator
Diode Laser Modules
Line generators from Coherent project a clean, sharp
line ~1 mm wide, with the line length represented by
the specific fan angle. With fan angles of 15, 40, 60 or
85 degrees, wavelength options ranging from 635 nm
to 670 nm, and various output powers available, line
generators from Coherent offer the options you need
for your particular application.
Focusable line generators deliver sharp lines with
adjustable line width, while the length of the line
remains the same fan angle. The line can be typically
focused as small as <0.1 mm at a distance of 10 cm or
can be focused to as small as ~0.4 mm at a distance of
1 meter.
For lasers without a connector, order plug no. 1057734.
Compact, Rugged and Reliable
Our miniature laser modules are superb choices for
many applications demanding affordable, compact
lasers. Using AlignLock technology, all modules are
optimized for thermal conductivity, protected from
mechanical shock and deliver superior pointing
accuracy and stability. These compact, rugged and
reliable diode laser sources also have a sophisticated
internal driver/controller circuit, which provides both
surge and reverse polarity protection. The nominal
operating temperature range is -10 to +40°C. Diode
lifetime will be greater at lower temperatures.
Use the appropriate LabLaser mount [part no. 0221449-00]; VLM2 mount [part no. 0221-437-00]; or VLM3
mount [part no. 0221-448-00] for convenient heat
sinking and mounting with adjustable alignment.
The LabLaser used in conjunction with the LabLaser
Power Supply [part no. 31-1050-000] provides a
complete CDRH-compliant system with all the safety
features, including 5-second power-on delay, interlock
and key switch.

Miniature
Diode Laser Modules
Circular and elliptical miniature diode laser modules
provide the smallest package size and best value.
Included inside every module are complete electronics
to manage the constant power laser drive with a
closed-light loop based on an internal photodiode.
Also included in the electronics are protection circuits
to provide a robust system in even the smallest of
packages.
Miniature diode laser modules use the patented
AlignLock technology to guarantee beam-pointing
alignment of <4.3 mrad. This allows for simpler and
easier integration, as you can trust the unit-to-unit
consistency of each beam.
Use the appropriate VLM2 mount [part no. 0221-43700] or the VLM3 mount [part no. 0221-448-00] for
convenient heat sinking and mounting with adjustable
alignment.
Miniature elliptical diode laser modules offer
exceptional beam quality with a typical M2 of 1.4
or better in a typical 1 x 3 aspect ratio.
Compact, Rugged and Reliable
Our miniature laser modules are superb choices for
many applications demanding affordable, compact
lasers. Using AlignLock technology, all modules are
optimized for thermal conductivity, protected from
mechanical shock and deliver superior pointing
accuracy and stability. These compact, rugged and
reliable diode laser sources also have a sophisticated
internal driver/controller circuit, which provides both
surge and reverse polarity protection. The nominal
operating temperature range is -10 to +40°C. Diode
lifetime will be greater at lower temperatures.
For lasers without a connector, order plug no. 1057734.
Miniature VLM2 circular diode laser modules create a
1 mm circular output beam using MicroBlaze patented
technology. This is a technique that accurately
positions a fiber micro-lens inside the diode laser cap.
The micro-lens uniquely corrects the divergence of the
fast axis. Once corrected, the beam shape changes
from elliptical to circular, providing maximum power
transmission and less astigmatism than other
methods. Diode modules with a 3 mm beam are also
available. These modules feature a multi-element
spatial filter that produces a large, clean, circular beam
with an ~3 mm diameter.
26
•
www.Coherent.com
Circular 1 mm Beam
Circular diode laser modules produce a ~1 mm
near-diffraction-limited beam. The circular lowdivergence beams have almost no astigmatism and
a total wave-front error typically less than λ/10.
The M2 beam quality factor is typically 1.2 or better.
These diode laser modules produce a beam of such
high quality that they can replace more expensive
HeNe lasers in many applications. Circular diode
laser modules are also smaller, require less power
and generate less heat than traditional HeNe laser
sources.

MVP Control
Diode Laser Modules
Modules with Modulation and Variable Power (MVP)
deliver high-brightness, low-divergence beams with
wavelength choices from 635 nm to 830 nm. Rugged
packaging encloses index-guided, single-mode diodes,
high-quality optics and sophisticated electronics with
MVP control. The MVP is a third-wire control for
modulation and variable power from DC to >500 kHz.
These VLM laser modules are ideal for long-life
laboratory and instrument applications.
Digital control is accomplished by sending a square
wave into the control input. The zero-to-5V square wave
drives the laser from ‘Off’ to full output power. For
analog signals the laser responds with high fidelity
when the drive is analog and applied into the control
input in the range of 1.8V to 3.2V.
Use the appropriate LabLaser mount [part no. 0221449-00] or VLM2 mount [part no. 0221-437-00] for
convenient heat sinking and mounting with adjustable
alignment. For lasers without a connector, order plug
no. 1057734.
The LabLaser MVP used in conjunction with the
LabLaser Power Supply [part no. 31-1050-000] provide
a complete CDRH-compliant system with all the safety
features including 5-second power-on delay, interlock
and key switch. The front panel knob on the power
supply can control the laser power.
The LabLaser MVP can use an external signal to
control the laser power. The signal can be connected
to the laser with the optional interface cable [part no.
31-1068-000]. Please note that when using the optional
interface cable that the front panel power control knob
on the LabLaser power supply [part no. 31-1050-000]
will not function. Instead, the laser is responding only
to the external signal.

laser with the optional interface cable part no. 31-1068-000.
Please note that when using the optional interface cable that the
front panel power control knob on the part no. 31-1050-000
power supply will not function – instead, the laser is only
responding to the external signal.

Diode LabLaser
Universal Power Supply
The Diode LabLaser™ Universal Power Supply provides a
well-regulated 6 VDC, 250 mA output for driving any of
the Coherent Diode LabLasers with the additional
benefit of variable power control. To vary the output
power of the Diode LabLasers which incorporate the
Variable Power and Modulation Control circuitry simply
adjust the multi-turn knob on the front panel of the
31-1050 power supply. This varies a voltage on the “third
wire” connection in the laser cables and the laser
power can be smoothly varied between threshold and
the rated power. The supply incorporates CDRH safety
features (keylock, power-on indicator, 4-6 second
emission time delay and remote interlock socket), is
CE-marked and meets appropriate UL, CSA, and EN
requirements.
This compact (120 x 76 x 48 mm) power supply can
be connected to any 90-130 or 180-260 VAC 50/60 Hz
supply. There is an IEC 320 input socket and a 1.8 m
detachable line cord with plug provided. The output
to the laser features an easy connect/disconnect
3-terminal jack socket on the front panel which mates
to the male plugs of the cables connected to all
Diode LabLasers.

500 kHz Modulation
Bandwidth
To modulate the laser power disconnect the “third wire”
power-control (incorporated in the laser cable and jack,
and power supply socket) and apply the desired AC/DC
modulation in its place. This is simply done by inserting the
special Modulation Interface Cable 31-1068 between the
cable jack and power supply socket and applying the
modulation to the BNC socket attached to the cable. The
control should be TTL, or 5V for full laser power, or varied
over the range 1.8 to 3.2V for analog linear modulation.
Bandwidth is ~500 kHz. Full details are supplied with the
LabLasers which incorporate the Variable Power and
Modulation Control circuitry.

Variable Angle
Diode Laser Mounts
Coherent’s variable angle laser diode module mounts
are designed to accept three different sizes of diode
laser module namely VLM3, VLM2 and LabLasers (9.5
mm, 14.8 mm and 19.0 mm diameter).
This simple mount acts as combined heat sink,
electrical insulator and variable-angle mount for 9.5
or 14.8 mm diameter diode modules and 19.0 mm
Diode LabLasers. The lasers are held firmly in a
spherical-surface brass ring by two small set screws.
This ring is clamped between two insulating blocks
forming a “ball and socket” arrangement. Two sockethead screws can be loosened to allow easy angular
adjustment of the module (±15° range) and quick, rigid
locking in position.
